Duke is a well mannered Jack Russell. He and his life-long friend, Daisy, a rat terrier (listed seperately), were surrendered to be rehomed. Duke is about 7 years old, crate trained, altered, and up to date on shots. Daisy n Duke lived the life ... until a 'family' came along. Now mom and dad don't have enough time for them. It was good that they realized it and have opted to find a new caretaker that can give them the time they need. Things You Should Know: A fenced-in yard will often not be enough for these dogs. Though small, they can leap very high and have been known to jump fences when they get bored and restless. On a walk, always keep them on a leash. They are incredibly fast, plus they have an intense curiosity and a fearlessness that could get them into trouble with bigger dogs. Jack Russell Terriers get along fine with the whole family. They are perky, lively and fiercely protective of their environments. And they make great guard dogs: A stranger approaching the house will be met with relentless barking. Not only are they useful, they can beÂwith the proper focus and trainingÂexcellent members of the family: loyal, loving and fun. A healthy Jack Russell can live as long as 15 years. Common health issues include cataracts and joint problems, but this is a solid breed with relatively few health issues. IndyCLAW Rescue, Inc. - Creating Life-long Animal Welfare.
